14 Claims. (Cl. 222-94) My invention relates to dispensing fluentmaterials, such as pastes and the like, and in particular provides adevice for dispensing two or more such materials simultaneously.

Thus it is a principal object of my invention to provide a device fordispensing, two or more materials of different color as a color stripedstream for the. purpose of presenting the dispensed materials inattractive product 'form. In this aspect of my invention, I particularlycontemplate providing a color striped tooth paste product for the.purpose of encouraging children to clean their teeth. In addition thedevice is useful in cake. decorating, candy manufacture and. in themanufacturev of. other food products, cosmetics'and the like where a,color stripe effect is desirable for ornamental purposes. Generally informin'g'color striped products with the device of. my in.- ventioncoloring materials, such as food dyes, are added to different portionsof the same base material to achieve the color effect desired.

It is also a principal object of my invention to provide a device fordispensing a striped stream of two or more materials which differ insome other characteristic in addition to color or which diifer in somecharacteristic other than color. In this aspect of my invention, 1particularly contemplate dispensing materials simultaneously which,because they tend to degrade upon contact with each other, must beseparately stored prior to dispensing. Thus, for example, it isfrequently desirable to add to cos..- metics, dentifrices and similarmaterials active ingredients, such as certain vitamins, which rapidlydeterioratev upon dilution in the particular base material. My inventionpermits such base materials and additives to be, stored separately in asingle container and dispensed simultaneously.

In addition to these general objects of my invention. it is a furtherobject of my invention to provide a. device of the general characterdescribed which is simply fabricated, filled and assembled and. whichassures dispensing of. the several materials in constant proportion, oneto the other.

It is still another object of my invention to provide a dispensingdevice of the general character described which can be constructed todispense two or more materials simultaneously as a. single stream. inwhich the striping of one material inthe other can be located in thestream at a single or plurality of positions. either at the surface ofthe stream or within the stream, or both.

It is yet a further purpose. of my invention to provide adevice of the.general character. described which can usefully be employed indispensing of materials from collapsible containers or from rigid.containers assisted byan impeller, such as a piston, or which can beem.- ployed to add a stripe ofa difierentmaterial or co.lor, or both, toa stream of material dispensed from anentirely separate container.

- It is still a further object of my invention to provide bio ofsimultaneously dispensing materials" of different consistency, forexample, in striping a paste-like material with a thin liquid.

These and other objects of my invention are generally obtained utilizingthe arrangement which is the subject matter of United States Patent2,789,731 to Leonard L. Marrafino, by which. pressure applied to afluent material 'retainedin, a chamber is transmitted by the material toat least a'second fluent material which is retained in the same chamberas the first to dispense. each material through separate dischargepassageways which eventually lead to the same outlet orifice. Thedevices constructed in accordance with my invention, however, differfrom those specifically described in the aforenoted patent in thatv thepresent devices do not pass the stream. of the first material throughthe center of the second material as in the specific devices of thepatent. Specifically I contemplate storing the second material. ormaterials in a vessel which is supported in a main chamber adjacent toand spaced from the inner endfof a main discharge passageway such thatmovement of the first body of material from the main chamber passesaround the outside of the vessel and then into the main dischargepassageway. Discharge of material from the small vessel, which is opento the interior of the main chamber at a point remote from the dischargepassageway is accomplished by providing onev or more legs, each having aconduit which communicates with the interior of the vessel and leadsthrough thelegs. or legs into the main discharge passageway. As pressureis applied to the body of material in the main chamber it is thustransmitted. by the material to the contents of. the vessel and as. thebody of material is. dispensed from the main chamber around the vesseland into the discharge passageway the. contents of the vessel are forcedto flow out through the leg or legs forming a stripe in the dis.- pensedstream of the material wherever a leg. terminates. Simply by properpositioning of the leg or legs the. material from the vessel can beintroduced into the dispensed stream at any desired location.

For a more complete understanding of the practical application of theprinciples of. my invention reference is made to the appended drawingsin which:

Referring to Figure 1 the reference numeral 10 desig; nates acollapsible container of conventional construction. Container 10includes a tapered neck end 11 havingcylindrical nozzle 12 at its apexsuitably provided with. ex. ternal threads 13 for receiving a'cap.' Themain body of container 16 is formed by a cylindrical. side Wall. 1.4attached at one end to neck 11 and'closed'together' at its-other end asindicated by the reference numeral 15. Suitably container is fabricatedin one piece of a flexible material, such as lead, and is formed morethickly atneck 11 and nozzle 12 than at side wall14 to impart a greaterdegree of rigidity to neck 11 and nozzle 12. Nozzle 12 is provided witha wide axial bore 16 forming a discharge passageway 18 leading into amain chamber 17 confined by neck 11 and side walls 14.

Positioned within neck 11 is a vessel 29 having a conical 'side wall 21which is spaced from theinner wall of neck 11 forming a passageway 22 ofannular cross-section leading from chamber 17 to discharge passageway18. Thebottom 23 of vessel is entirely closed except "amass? v Figure 3illustrates a device similar to that shown in Figures 1- and 2 forattachment to the discharge nozzle 'as otherwise noted below and islocated adjacent to and spaced a short distance from dischargepassageway 18. Thus passageway 22 freely communicates with dischargepassageway 18. v I Four legs 24 are attached to bottom 23 ofvessel 20spaced at equal arcuate intervals about its edge and extend parallel toeach other into discharge passageway 18. Legs 24 are arranged to fittightly within bore 16 and thus support vessel 20 in the positiondescribed above.

Each of legs 24 is provided with a bore 25 extending through the entirelength of its respective leg 24 and extending through bottom 23 at oneend, as indicated by the reference numeral 26, thus communicating theinterior 27 of vessel 29 with discharge passageway 18. Preferably theend faces of legs 24 remote from vessel 20, through which bores 25 openinto discharge passageway 18, are faced inwardly on a slant and are setback a short distance from the outer end of bore 16. v

A flexible, non-porous diaphragm, constructed of rubher or similarmaterial, is placed inside the wide end of sidewalls 21 to' cover theinterior 27. of vessel 20. Referring to FigureZ' which shows the samedevice as Figure 1 the interior 27 of vessel 28 is filled with amateriaLsuch as 'red tooth paste, and chamber 17 is filled with anothermaterial, such as white tooth paste. It will be noted that the wide endof vessel 20, that is, the end which is'remote from discharge passageway18, is freely open to the interior of chamber 17. Ordinarily where thematerials in chambers 17 and 27 do not tend to degrade upon contactdiaphragm 28 can be omitted. If, how ever, there is a tendency ofdeterioration of one material upon contact with the other, for example,if the red dye employed in coloring the tooth paste in chamber 27 tendsto bleed into the white material, it is preferable to separate the twomaterials using flexible diaphragm 28. Alternatively a layer of flexiblewax can be sprayed on the exposedsurface of the material in vessel 20,or the same surface can be covered by a layer of inert fluent material,such as petroleum jelly.

When it is desired to employ container 10 side walls 14 are squeezed inthe conventional manner. This forces the body of white materialcontained in chamber 17 to move toward discharge passageway 18. Most ofthe material so moved will flow through passageway 22 be tween legs 24into passageway 18 causing a rod of material to stream forth from nozzle12. Some of the white material will be displaced, however, into the openend of vessel 20 forcing the red material retained in chamber 27 throughopenings 26 into bores 25 eventually forming stripes on the surface ofthe rod of material streaming from nozzle 12. If a flexible covering,such as diaphragm 28, is employed it will flex toward the bottom 23 ofvessel 20 as the contents of container 10 are thus dispensed. It will benoted that the inwardly slanted end faces of legs 24 facilitate movementof the stream of stripe material to the outer surface of the main rodissuing from discharge nozzle 12. If the end faces had been terminatedwithout this slant there would be a tendency for the striped stream topenetrate more deeply into the rod. This result can, of course, be alsoavoided where it is not desired by providing an inwardly extendingflange at the outer end of bore 12. l

49 of a typical aerosol container 41 employed, for example, forcontaining cream and a suitable pressurizing and expanding agent.Typically slight lateral pressure against discharge nozzle 40 opens avalve in container 41 releasing a foamy cream product from dischargenozzle 46.

In this arrangement of my invention I utilize a rigid two piecereceiver42'j which is providedat one end with a fitting 43 having a bore.44 which can be wedged on .the exter'iorof discharge nozzle 46 suchthat the product discharged from container 41 will pass into theinterior chamber 45'ofg're'ceiver' 42. Atit's end opposite inlet 43receiver 42 is providedwith a cylindrical discharge nozzle 46 having abore 47 leading to the interior 45 of receiver 42. It will be noted asshown in the drawings receiver 42 comprises a lower shell 42a whichcarries inlet fitting 43 and an upper shell 42b. which carries dischargenozzle 46. These two pieces are' held together normally by a threadedjoint 42c.

A small vessel 48 is provided with an integral cylindrical side wall 49and upper end closure 50, and a snap 'fit cap 51 over its lower end.Four legs 52 extend upwardly from end 50 and are spaced parallel to eachother at arcuate intervals about the periphery of end 50. Vessel 48 ispositioned in receiver 42 with its end 50 adjacent to and spacedinwardly from the lower, inner end of bore 47 of discharge nozzle 46.Legs 52 thus extend into bore 47 frictionally engaging the wall of bore47 to hold vessel 48 in position. Legs 52 also extend downwardly fromend 50, as indicated by the reference numbers 53, into the space 54enclosed by side wall 49. v

A flexible, non-porous, thin diaphragm ,55 resting at its periphery inthe corner formed between side wall 49 and cap 51 extends across theopen bottom of vessel 48 above cap 51, and a small aperture 56 is formedat the center of cap 51. Legs 52 and their lower extensions 53 areprovided with bores 57 extending therethrough which communicate thespace 54 in vessel 48 with the interior of bore 47. Bores 57 as theyenter bore 47 are restricted in diameter as indicated at 57a.

To assemble the device shown in Figure 3, for example, to dispense acolor and flavor striped whipped cream product, space 54 of vessel 48,held in inverted position, is charged with a thin sugar syrup, suitablypeppermint flavored and colored with a pink dye. Diaphragm 55 is thenpositioned across the open end of vessel 48, and cap 51 is snapped onover the edges of side wall 49 to retain diaphragm 51. Vessel 48 is thenpositioned in upper shell 42b by forcing the end portions of legs 52into bore 47 from within upper shell 42b. Shells 42a and 42b arethreaded together, and receiver 42 is then inverted and aflixed toaerosol can 41 by wedging nozzle 40 of can 41 into bore 44 of inletfitting 43, as shown in Figure 3.

It will be evident that the device shown in Figure 3 is particularlysuitable for striping aerosol products which are dispensed from theconventional upright can, because of the extension of leg portions 53into the interior 54 of vessel 48. Also because of such extension,liquid striping materials can be handled, even when receiver 48 isinverted. It will also be noted that the lower ends of leg portions 53are inclined inwardly and upwardly to permit diaphragm 55 to stretchinto space 54. The principal purpose of aperture 56 is to reduce theimpact of aerosol product against diaphragm 55 where the stripingmaterial is a thin liquid. Accordingly more than one such aperture canbe employed, where desired, cap 51 can be omitted and replaced simply bya retaining ring.

When the striped aerosol product is to be dispensed, lateral force isapplied to receiver 42 causing nozzle 40 to bend thus opening the valvein can 41 in the conventional manner. Whipped cream product is thereupondispensed under the internal pressure of can 41 through nozzle 40 intointerior 45 of receiver 42. As the harass? whipped cream product fills;interior 45, 'ilZ'llOWS past'the Space between side wall 49 of vessel 48and the. inner wall of shell 42b, between legs 52 and out through here47 of discharge nozzle 46. At the same time a small amount of whippedcream enters aperture 56 causing the center of diaphragm" 55 to flexupwardly (see dashed lines iii-Figure 3) displacing thecolored andflavored material in space 54 of vessel 48 to flow out through bores 57of legs 52-53 into bore 47 of discharge nozzle 46 in four distinctstreams. Hence, as the whipped cream product is dispensed from dischargenozzle 46, the surface of the discharged product carries four distinctpink stripes having a peppermint flavor. Dia phragm 55 returns to itsoriginal shape upon release of pressure. When pressure again isintroduced diaphragm 55 acts as a piston and pushes out more stripematerial.

It will also be evident that the structure of vessel 20 in Figures 1 and2 and of vessel 48 in Figure 3 can be varied substantially to providealternate modes of sup porting the vessel. Thus. in Figure 4, whichshows a fragmentary view of container 10 shown in Figures 1 and 2, avessel 60 is shown in place of vessel 20. Vessel 60 has a conical sidewall 61 and is provided with a leg. 62 attached at the apex end of sidewall 61 extending centrally into discharge passageway 18 formed in bore16 of discharge nozzle. 12 of container 10. Leg 62 is hollow and opensat its end attached to vessel 60 to communicate its interior 63 with theinterior 64 of vessel 60. 1

The end of leg 62 adjacent to the outlet end of discharge nozzle 12 isclosed and carries four angularly disposed feet 65 which are attached toleg 62 at equal arcuate intervals about its closed end and which lead attheir outer ends to the inner wall of discharge nozzle 12 which definesbore 16. Each foot 65 is "bored, as indicated by the reference numeral66, to communicate at its inner end with interior 63 of leg 62. Each ofbores 66 at-the outer end of its respective foot 65 is turned toward theorifice end of discharge nozzle 12 and opens into bore 16.

A ring 67 supported by spaced spokes 68 is traverse ly mounted on leg 62as hub end is frictionallyreceived in bore 16 at its periphery thussupporting vessel 60 in neck 11 of container 10.

The functioning of the device shown in Figure 4 is substantially thatdescribed above with respect to vessel 20.

Figure shows another modification of vessel 20 in which the legstructure is formed from a tube in order to give superior support forthe vessel in the bore of the discharge nozzle of a suitable containeror other receiver.

In Figure 5 a vessel 70 is provided having a conical side wall 71 closedacross its bottom 72 and carrying a tube 73 on its bottom 72 suitablyformed as an integral piece with side wall 71 and bottom 72. Tube 73 hasan outside diameter which will be tightly received in a discharge nozzlesuch as nozzle 12 of Figure 1. Tube 73, adjacent to bottom 72, isprovided with four windows 74 spaced at arcuate intervals about tube 73defining four legs 75 extending from the bottom 72 of vessel 70. Each oflegs 75 is provided with a bore 76 which communicates at one end withthe interior 77 of vessel 70 enclosed by side walls 71, and each bore 76extends at its other end lengthwise through tube 73 opening in the edgeof tube 73 remote from, bottom 72 of vessel 70.

Vessel 70 is employed in a manner identical to vessel 20, for example,but the rigidtubular construction permits a tighter forcefit'with'inbore 16 f o r"s ecuring vessel 70 in position in the neck 1--1 oficontainer 10. The interior; 78 of tube 73, thus defines, the dischargepassageway for the main body of material from container which isaccessible through windows 74 which in assembled position lie withintapered neck 11 of container 10.

Figure 6 shows still another modification of the cont6 struction ofvessel 20. In Figure 6 the vessel for re'ceiv ing the striped materialis designated by the reference numeral and includes a hemispherical sidewall 81 from the center of which extends a tubular leg 82. The openinterior 83 of leg 82 communicates with the interior 84 of vessel 80enclosed by side wall 81. The lower end of leg 82 is closed and carriesfour radial spokes 35 which support at their outer ends a ring 86.Vessel 80 is supported in container 10, for example, by wed'ging the rimor" ring 86 in bore 16 such that leg 82 is centrally positioned indischarge passageway 18 and side wall 81 lies in neck 11 spaced a shortdistance therefrom. The structure of Figure 6 is completed by fourpassageways 87 each of which extends through a spoke 8'5 and commuuicates at its inner end with interior 83 of leg 82 and at its outerend exits from the under surface of ring 86.

When the device of Figure 6 is employed the flow of base materialthrough discharge passageway 18 isabout leg 82 and through the spacesbetween spokes 85, whereas the flow of striping material runs frominterior 84 of vessel 80 through the interior 83 of leg 82 and then outthrough passageways 87.

Figure 7 shows yet another construction in accordance with my invention.The vessel for receiving the striping material is formed of moldedplastic integrally with the discharge end 101 of a container 100.Discharge end 101 includes a tubular discharge nozzle 102, havingexternal threads 103 at. one end for receiving a cap. Nozzle 102encloses a discharge passageway 104 and is centrally provided with anoutwardly extending radial flange 105. On the opposite end of dischargeend piece 101 from threaded end 103, tube 162 is longitudinally slottedto formfour equally spaced struts 106 which are attached at their endsto the disk bottom 107 of a conical vessel 108 which is open at itsupper, wide end.

Bottoin 1 07 of-yess'el'108 centrally carries a leg 109 which'isprovided with a longitudinal bore 110 opening at one end through bottom107 to. communicate with the, interior 111 of vessel 108 and opening atits other end in discharge passageway 104.

The body of container is formed of tubular flexible metal stock and isnormally assembled by bending in one end to form a neck 112 which iscrimped upon the outer edge of flange as indicated by the referencenumeral 113 forming a passageway 114 of annular transversesec tionbetween neck 112 and vessel 108 which communicates between the interior115 of container 100 and dis, charge passageway 104 through the spacesin tube 102 between struts 106.

, From the preceding description of the device shown in Figure 7, itwill be apparent that its functioning is identi' cal to that, forexample, of the devices shown in Figures 1 and 2 except that materialretained in the interior 111 of vessel 108 will be extruded as acentered stripe or core and the base material in chamber 115 will formthe surface layer of the dispensed product.

Figure 8 illustrates another modification for striping a productdispensed from an aerosol container. The device shown in Figure 8, likethat in Figure 3 is particularly suited to liquid striping materials,but unlike that, of Figure 3 can be employed in any position, and hencecan be employed with the type of conventional aerosol containers whichare designed to be employed in inverted position.

In the modification of Figure 8 I utilize a two piece receiver which isprovided at one end with a fitting 121 having a bore 122 which receivesthe discharge nozzle of a conventional aerosol container. At its otherend receiver 120 has a cylindrical discharge nozzle 123 provided with abore 124. The shell of receiver 120 includes a base cap 125 on whichinlet fitting 121 is formed and a housing 126 from which dischargenozzle 123 extends. Base cap 125 snap fits over housing 126 to enclosean interior space 127 between them which communicates atone end withbore122 of fitting 121 and at the other end with bore 124 of nozzle 123. I

, "A small vessel 128 in the form of a cylindrical block 129 having adeep conical end depression 130 in its lower end and four upright,parallel legs 131 extending above its top end surface 132 is positionedin receiver 120 with the upper portions oflegs 131 cemented to the sidesof bore 124 of discharge nozzle 123. ,An annular lower edge'132 isformed on the bottom end of block 129 be tween its cylindrical outerside wall 129a and its conical inner wall 129b, Four bores 133 eachextend from an opening in edge 132 upwardly through a leg 131 andterminate in a restricted opening 134 in the inwardly and downwardlyinclined upper end face 135 of the associated leg 131. Four channels,-i.e., grooves, 136 each extendfrom the bottom to the top of the inner wall129.11 adjacent to a bore 133, and a small slot 137 iscut in annularvedge 132 connecting each bore 133 with one such channel 136.

' -Receiver 120 is charged and assembled by first filling depression 136with the liquid striping material while the assembled housing 126 andvessel 128 are held in inverted position from that shown in Figure 8. Athin, elastic piece of material, such as rubber, is then placed overdepression 130 with the edges of the material extending beyond annularedge 132. A ring 138 is then placed over the end of vessel 128 to wedgethe edges of the rubber or other material between ring 138 andcylindrical outer wall 129a, stretching the material over depression 130as a diaphragm 139. Base cap 125 is then snapped onto housing 126 andthe device is ready for employment inthe same manner as receiver 42 inFigure 3. a Pressure of an aerosol product introduced through fitting121 causes diaphragm 139 to flex inwardly forcing the contents ofdepression 130 out through slots 137 and up through bores 133 to stripethe aerosol product as it issues from discharge nozzle 123. Even whenreceiver 120 is held in inverted position, as diaphragm 139 flexesinwardly to fill depression 130, the striping material rides up channels136 to enter slots 137 and bores 133, since diaphragm 139, as it flexesinwardly, rides against the inner wall 129!) of block 129 closing thesides of channels 136 to make suitable conduits of channels 136.

From a review of the preceding description it will be evident that thedevice of my invention is capable of modification in many ways and isgenerally applicable to dispensing two or more materials simultaneouslyin any desired transverse pattern. Dispensing of more than two materialscan be accomplished, for example, by compartmenting the inner vessel topermit storage of separate striping materials associated with separatefeed legs or by nesting several vessels coaxially and spaced from eachother.
